private baseUrl='https://localhost:7125/api';
getFilePath(url:string){
  return `${this.baseUrl}/${url}`;
}

code TS File:

public   setFile(): void {
//this.AllDemande.fileUrl : url link form database
      if(this.AllDemande.fileUrl=!null){
     this.DisplayFileUrl= this.congeService.getFilePath(this.AllDemande.fileUrl);
       }
      else{
